  • Spread spectrum time tracking
    Patent number: 6873667
    Abstract: Time tracking units with decision statistics mitigating or correcting for influences from nearby interfering paths. Interference mitigation is accomplished by appropriately selecting the parameters of the time tracking unit so that the contribution of the interference on the decision statistics of the time tracking unit is minimized. Interference cancellation is accomplished by evaluating and subtracting of the effect from the interfering paths on the decision statistics of the time tracking unit. Both urban and indoor communications may incorporate the interference avoidance or interference correction either in each time tracking unit of a rake-type receiver by inter-unit communication of timing adjustments and path energies or by software within a common processor.

  • Use of Walsh-Hadamard transform for forward link multiuser detection in CDMA systems
    Patent number: 6798737
    Abstract: A station capable of receiving information containing Walsh coding for a plurality of channels and canceling interference from the received information and the method of cancellation. A memory is provided for storing received signals containing a Walsh code for each of a plurality of channels as well as reflected and/or refracted versions of said received signals and a first plurality of signal paths is provided which are selectively coupled to the memory. The signal paths apply corresponding delays and inverse Walsh code transformations to separate the channels. Further, cancellation of the channels interfering with a desired channel proceeds with complementary delays and Walsh code transformation to regenerate the interference which is subtracted from the received signal in memory.
